GAS-GENERATING OIL-BURNER.

Specification of Letters Patent.

Patented May 30, 1911.

Application filed. October 17, 1910. Serial No. 587,439.

I '0 all whom it may concern:

Be it known that we, JOHN Brennan and JOHN D. VLWIAN, citizens of theUnited States, residing at Minneapolis, in the county of Hennepin andState of Minnesota, have invented certain new and useful Improvements inGas-Generating OilBurners; and we do hereby declare the following to bea full, clear, and exact description of the invention, such aS willenable others skilled in the art to which it appertains to make and usethe same.

Our invention has for its object to pro vide an improved gas generatingoil burner and, to this end, the invention consists of the novel devicesand combinations of de vices hereinafter described and defined in theclaim.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure l is a view chiefly in verticalsection, but with some parts shown in full and some parts broken away,illustrating our improved burner applied in the fire box of a range orcooking stove; and Fig. 2 is a plan view of the burner showing portionsof the stove in horizontal section.

The numeral 1 indicates, as an entirety, the fire box of the range orcooking stove to which the burner is shown as applied. The burnercomprises a hollow annular shell 2, which is preferably cast and affordsa generating chamber having an axial passage 3 extending verticallytherethrough. The oil from an elevated tank or other source forsupplying the oil under pressure, is delivered through a supply passageat which is connected to the generating chamber of the shell 2, as shownthrough a pipe coupling A horizontally disposed mixing tube 6 isconnected by an elbow 7 to the axial passage 3 of the shell 2. A nozzle8 is positioned for delivery directly into the open end of the mixingtube 6, and this nozzle is connected by a pipe 9 to one side of thegenerating chamber of the shell 2. The discharge orifice of the nozzle 8is adapted to be opened and closed by a suitable valve 10, preferably ofthe needle valve type. A drip pan 11 is placed in the bottom of the firebox 1 and is preferably rigidly attached to the bottom portions of theelbow 7 and nozzle 8.

A small L-shaped pedestal 12 is pivotally connected, at its lower end,to a projecting lug 13 of the shell 2 with its horizontal up per portionnormally extending above the axial passage 3 of the said shell 2. Adisklike deflecting plate 14: is supported by the lower end of a hanger15, which is adjustably mounted on the horizontal upper portion of thepedestal 12. Normally, or ordinarily, this deflector plate 14: will bepositioned with its axis alined with the axis of the shell passage 3,but spaced above the shell so as to properly spread the flame whichstrikes the same. This deflector may, however, be turned at one side ofthe passage 3. and thereby thrown out of action at will.

By reference to Fig. 1, it will be noted that the passage 3 and thedeflector (when the latter is in normal position) are located axiallydirectly under one of the stove lids 1, so that when the latter isremoved, the flames spread by the deflector 14 will be evenlydistributed under the open lid hole. The greatest heating effect will beproduced when the deflector is in the working posi tion as shown and,hence, the deflector will be positioned for action when the stove isused for baking or heating purposes. Sometimes, however, when thecooking utensil is placed in the open hole over the burner, the bestresults can be obtained by turning the deflector to one side so that theflame will directly strike the bottom of such utensil. In this lattercase, therefore, the axial location of the passage 3 in respect to thelid opening is highly important.

The improved burner may be applied to any range or cooking stove or toother stoves, for that matter, very easily and at small cost. In mostinstances, the burners will be applied one under each of the holes thatdirectly overlie the tire box of the stove.

This improved burner was especially designed to generate gas fromkerosene and to burn the same, but it may be used to generate and burngas formed from other oils.

The shell 2 of the generating chamber is shown as provided with openingsclosed by detachable plugs 18, so that, when desired, one or moreadditional gas burners may be coupled to the generating chamber andsupplied with gas therefrom. For the convenient attachment of the burnerto the range or cooking stove, the drip pan 11 and nozzle 8 are shown asattached to a plate 16 which closes one end of the fire box and is heldin place by adjustable turn buttons 17. To start the burner, a smallamount of the oil will be allowed to run into the drip pan 11, byopening the valve 10, while the burner is cold. The loose oil in thedrip pan being ignited will heat the generating shell 2 and pipe 9 andgenerate gas therein. Then, when the gas has been generated, the valve10, which should be closed during the initial generation of gas, will beagain opened and gas will then be discharged from the nozzle 8 into themixing tube 6. Air will be drawn into the open end of the mixing tube 6with the gas and will thus afford the necessary oxygen required tosupport complete combustion. The heat produced by the burner, ingenerating the gas, will maintain a suilicient generation of gas, sothat, after the burner has been properly started, the liquid fuel burnedwill be in gaseous form instead of in liquid form.

In actual practice, the ei'ficiency of the improved burner abovedescribed has been demonstrated.

WVhat we claim is:

In a gas generating burner, the combination with an annular generatingchamber having an axial passage, of a mixing tube connected to the axialpassage thereof, an oil supply pipe leading to said annular generatingchamber, a nozzle connected to said generating chamber and positioned todischarge into the said mixing tube, a supporting pedestal pivoted tosaid generating chamber and having an upper portion adapted to belocated over the axial passage of said generating chamber, and adeflecting plate suspended from the upper portion of said pedestal andadjustable 'thereon, substantially as described.

In testimony whereof we aliix our signatures in presence of twowitnesses.
